yeah I've run into a couple of people using redis with karaf. One guy was using it together with spring which doesn't help me much. I did find this page: https://github.com/sneakybeaky/karaf-jedis Which gives an example of how to install the redis bundle. I tried it and it gives me two problems. One is that it uses a really old version of the pool library that would conflict with my newer version of Hikari, now that I'm using Bone its less of an issue but worth keeping in mind. Second problem is more serious: karaf@root()> install -s mvn:redis.clients/com.ninedemons.jedis/2.1.0-SNAPSHOT Bundle IDs: Error executing command: Error installing bundles: Unable to install bundle mvn:redis.clients/com.ninedemons.jedis/2.1.0-SNAPSHOT Caused by: java.io.IOException: Error resolving artifact redis.clients:com.ninedemons.jedis:jar:2.1.0-SNAPSHOT: Could not find artifact redis.clients:com.ninedemons.jedis:jar:2.1.0-SNAPSHOT in apache (http://repository.apache.org/content/groups/snapshots-group/) looks like the bundle no longer exists.
